Agent Orange

Duane Wiskus, 67, grew up in Carroll, Iowa, and served in Vietnam as a crew chief for EC-47 surveillance aircraft aircraft flying electronic eavesdropping missions out of Nha Trang in 1968-69, where he recalls helicopters spraying Agent Orange around the perimeter of his base as well as in the jungles of Vietnam. His son contracted infantile muscular dystrophy and died at 20-months-old — which he said he blames on his wartime exposure to Agent Orange. In recent years, he has had multiple heart attacks and deals with diabetes. BRENDAN SULLIVAN/THE WORLD-HERALD
